ROBINSON, — NEW SPERMATOPHYTES, CHIEFLY FROM MEXICO. 21 
tomentulosis ; foliis inferioribus petiolatis, summis sessilibus ; inflores- 
centiis t mboso-cymosis tomentosis ; capitulis numerosis 
8-9 mm. altis heterogamis calyculatis ; involucri campanulati squamis 
ca. 13 lineari-lanceolatis 5 mm. longis acutis nigro-penicillatis ceterum 
glabratis vel sparsissime tomentulosis ; floribus femineis liguliferis 5-8, 
-corollis glabris, ligulis flavis ; floribus disci ca. 25; achaeniis cano- 
hirtellis. — Barranca below Sandia Station, Durango, Mexico, alt. 2135 
m., 15 October, 1905, C. G. Pringle, no. 10,105 (type, in hb. Gray). 
This species has the general aspect of S. eremophilus Richards., S. chi- 
huahuensis Wats. and S. MacDougalii Heller, but differs from all of 
them in being tomentulose throughout and in having narrower leaves 
with mostly simple slender and entire lateral teeth or divisions. 
Senecio (§ Tomentosi) loratifolius Greenman, n. sp., herbaceus 
perennis ; caulibus erectis 3 dm. altis lanato-tomentosis ; foliis alternis 
elongato-lanceolatis vel subloratis 0.5-1.7 dm. longis 4-12 mm. latis 
acutis vel obtusis integris membranaceis juventate supra arachnoideo- 
tomentosis denique glabratis subtus persistenter albo-tomentosis ; foliis 
inferioribus basi sensim angustatis et subpetiolatis, superioribus sessili- 
bus et amplexicaulibus ; inflorescentiis cymosis terminalibus ; capitulis 
paucis 8-9 mm. altis heterogamis calyculatis ; involucris campanulatis 
tomentosis, squamis ca. 13 lineari-lanceolatis 6-7 mm. longis ; flori- 
bus femineis ligulatis 8-12, corollis glabris flavis ; floribus disci ca. 
35 quam squamis involucri vix longioribus ; achaeniis hispidulis. — 
Mountains near Saltillo, Coahuila, Mexico, alt. 2133 m., 5 October, 
1905, C. G. Pringle, no. 13,676 (type, in hb. Gray). This species is 
related to S. umbraculiferus Watson, but differs, amply in foliar char- 
- acters, especially in having thinner leaf-texture, glabrate upper leaf- 
surface, and more distinctly amplexicaul upper leaves.
